MULTICOLQR-LOOM.

To all whom it may concern:

Be it known that I,- JEAN POINTU, de-

signer of textiles, of 10 Place Victor Hugo,

RoannefLoire, in the Republic of France,

have invented new and useful Improvements in Mnltic lor-Looms, of which the following is-a pecificza tion. 1nvent1on relates to multi-color looms rand has for its object the automatic chang- "pirns albnegj(Northrop type), when the ingofftlie shuttles with their pirns,' or. the

thread is nearly exhausted, irrespective of the color- ,of the thread and Without stopping the loom.

Briefly put, in my invention there are two shuttle boxes, each with several compartments, one of the boxes being either of-the" volving one could be used. The latter, dur- "ing the normal-course of weaving receives the shuttles in the same compartment, from which of course they are repicked; it only changes the compartment it presents to the picked shuttle when the weft in the last one received is exhausted. The exhausted shuttle is retained in the compartment it has entered, but is laced out of action by the rotation of the box, a new compartment already charged with a full shuttle having weft of the same color as that put out of action, being presented to the picker. The spent shuttle .is ejected from its compartment later on, when another replacement of shuttles is being made. 1

According to my invention, I use the card mechanism not only for its main purpose as above mentioned, but also in connection with the replacement ofa shuttle. Broadly speaking, this has already been done.

The characteristic of my invention is this however; the setting in action of the shuttle changing mechanism is determined by a card behind the one simultaneously presented to the mechanism controlling the rising box, that is to say, the one determining the color of the weft to be picked;

' The weft exhaustion indicator on a shuttle to do so by the card control. The card prism picks previously. The consequence of this shuttle is Specification of Letters Patent. Patented July 20, 1915. Application filed Mar 31, 1912. Serial No. 700,710.

' is operated when the shuttle is in the'rising box, but cannot produce any effect on the" shuttle changing mechanism until permitted moves so that a fresh card is presented to the mechanism controlling the rising box after an interval during which the batten has executed two to-and-fro movements or picks (in reverse directions and'since it 5 is a card behind this one w ich allows the indicating mechanism; to become effective, it

follows that the first stages of the shuttle changing'operations can be commenced at least two picks before the almost spent shuttle is picked from the rising to the revolving box. Obviously, from the preceding description, it will be seen that these operations can be commenced four or more is, that operations can be distributed over several picks, and during the last pick, prior to the replacement of the shuttle, only a few.

operations at the most have to be performed. Thus, when the momentcomes for the actual changing of the shuttle, everything has been gradually got ready in advance, and the" change is effected without any abnormal effort on the part of any member of the mechanism.

In the description which follows, and on the drawings, one way of carrying out the invention is set forth in. which the selection and changing of the shuttles with their pirns is operated electrically. A loom has been chosen working with four colors, having rising and revolving boxes, each box with. four compartments, at opposite extremities of the batten or going part these compartments are. provided with the necessary shuttle box swells to secure the shuttles. In the accompanying drawings: Figure 1 shows the diagram of electrical connections for the different members. 2 is a side view of the shuttle selector fixed on the right side of the loom, the driving mechanism being'to the left. Fig. 3 is a front View of the selector shown in Fig. 2. Fig. 4 is a view on an enlarged scale of the principal members of Fig.2. Fig. 5 is a horizontal section of a swell in one of the boxes. Fig. 6 is a vertical section of this box complete showing the electrical connections. Fig. 6 is an end view of a shuttle. Fig. 7 -is a side view of. the lower part of the members of the distributing mechanism for replacing the empty shuttles by full ones. Fig. 8 is a front View of these members. Fig. 9 is a side view, partly in section, of the upper'part of these members, and also of the shuttle supply magazine, the magazine being provided with a suitable number of shuttles for each compartment of the shuttle box, each set" of shuttles having threads of the requisite color. Figs. 10 to 13 are views of the guides of the shuttle supply magazine, Fig. 10 being a side elevat'lon looking toward the inner face of a guide, Figs. 11 and 12 being sections .on the planes 1111, 12l2, respectively, of Fig.-

10, looking toward the left, and Fig. 13 be-,'

loom working in the manner already known. Fig. 2a is a similar view, but-with the batten in its backward position, this figure also showing, by way of example, the disposition of the members at the time of the selection of the third shuttle and its fall on the distributer. Fig. 25 is also a similar view, but.

with the batten in its forward position during which it meets the distributer which moves in an opposite direction and so ap proaches it; the third shuttle being shown placed by the distributer in its compartment of the rotary box. Fig. 26 is detail view showing the means for holding the revolving box in proper position for receiving the shuttle being employed in the weaving.

In the form of the invention shown, shuttles are employed of the kind patented by me in my English patent, No. 4629 of 1910; this kind of shuttle is adapted to .permit of thepassage of an electrical current through itself, when thread of the shuttle is nearly exhausted, by the movement of a spring button (not shown) which makes contact with the contact plate 25 '6) on one side of the shuttle 26.

Throughout the separate views the same part is designated by the same reference character.

Referring more particularly to the drawings, the electrical connections can be easily traced; there are a number of compartments in the rising box A (Fig. 6), a like number of shuttles 26 and a circuit for each shuttle, each circuit comprising an electro-magnet 29, a circuit breaker or interrupter formed by one of a number of levers 1 turning on 'an axis 2 (common to all of the levers), and

leads connected as follows: From a source of current B, a lead runs to the electro-magnet, thence leads pass to terminals 2 1 (Figs.

1 and 5) thence via 20, each circuit connects.

to a swell 19, and so to a plate 25 on a shuttle 26 and through the shuttle to the opposite plate 27, (these connections are only established of course when the shuttle'is in its compartment, and has nearly spent all its weft). lip 23 and a ledge 23 to a terminal 28. It may be remarked that, except for the plates .25 and 27, the surface of the shuttle in contact with 23 is non-conducting, and further, that the plate 25 is insulated, as clearly shown from the adjacent portion of. the ledge 23. From the terminals 28, (Fig. 1),

each circuit is" carried to terminals 13, then.

at certain interyals, through one or other of the levers 1 to' the axis 2, and thus through a key K(when closed) to the source B. The key K is an interrupting device and normally stands open. When the batten is at the extreme end of its stroke, the battensupport strikes the head D andcloses the key, which is suitably inclos'ed to prevent damage by sparks. lit will be seen that the interrupter key K aforementioned, is controlled in such a 'manner that the current, in order ;to avoid any loss, passesonly when the batten presses the weft In'Fig. 2, which shows the shuttle selector,

11' is one of the levers aforesaid which oscil-' 'lates about the spindle 2, fixed on a housing 3' of the box 4 for the needles 5 of the lifting wires 6 which control the rising box. The needles 5 are adapted to enter the holes in the card 7 on the jacquard cylinder 15, when they are opposite to them, and the corresponding lifting wire 6 is then raised and produces the usual result, the cylinder being rotatably mounted on the shaft 17.

It will be understood that when the needle presses against the card 7, the hole provided From 27 each circuit extends via a in the card allows the needle to enter and I then frees the lifting wire-6 above the blade which raises this lifting wire and brings in front of the batten the division of the rising and falling shuttle box corresponding to this lifting wire and to this needle so as to make the necessary selection. There are as many needles 5, lifting wires 6, and selecting levers 1 as there are shuttles of different colors. The case is the same as regards the number of divisions of the shuttle box. These needles, lifting wires, and selecting levers are independent of each other and the same needlealways operates with the same lifting wire, the same selecting lever alv ay soperates with the same electromagnet 29, and the I same needle and selecting lever always act with the same division 'of the shuttle box. The selecting levers'l rest on the upper card which corresponds to the color of the shuttles which are being or are next tobe oper-' ated, for each principal .pattern card is formed of several perforated cards or bands,

hinged to and connected to each other, perforated with a hole corresponding to the as the needle 5, there being no-change in color necessary at this point of .the pattern.' Each perforated card or band represents two beats of the batten, that is,

the forward and backward movement of the same shuttle. However, if the needles strike the 10th band of the blue, the selecting levers rest on the card in which is perforated a hole corresponding to the division of the ris ing shuttle box containing the shuttle with white thread and the corresponding lever penetrates into the perforation. In either case the lever operatesif the corresponding shuttle of white thread is finished, that is, if the circuit hasalready been closed on its two faces. If this is the case, at the moment when the batten beats the cloth, the current, the'circuit beingclosed by the shuttle, second by one of the selecting levers at 9, and fed by the interrupting device or key K, passes-through the corresponding electro magnet and attracts the lever 30, which determines all the movements of the charging mechanism. The key being closed on the forward beat of the lay and the gap between corresponding contact 24 and 26 being closed by the exhausted shuttle, one of the magnets 29 is energized lifting the proper arm 37, which, as the lay swingsbackfmoves the magazine into position to deliver a shuttle with weft of the color corresponding to the next shuttle to be'used. The active shuttle is thrown back to the shifting shuttle box, the 'second card indicates the proper needle 5, the exhausted shuttle is brought to the level of the race lay and so returns to the magazine side of the loom. In the next forward beat of the lay a shuttle with weft, corresponding to that in the compartment of the revolving box is inserted in the forward compartment (Fig. 25) and on the rearward movement of the lay the revolving box is turned so as to bring the full shuttle to the top and to the'level of the race lay. The replenishing is now' complete and the full shuttle will be thrown across to the proper compartment of the shifting shuttle box. In the contrary case, everything remains unafiected. It 'willbe seen that jacquard cylinder 15 of the above describedmechanism is mounted on a shaft 17, which is rotated in a step by step manner by any convenient known mechanism (not shown). The cylinder- 15 is shown as four square in cross'section (see Fig. 1) so as to accommodate the card 7 on three sides. In order that th'etdifferent movements of withdrawal 'of the empty shuttle, of the descent of the corresponding shuttle onto the charging slide, and of placing the latter in the revolving box, shall be spread out over several beats of the battenfitis. indispensable that there should not befa controlling relation between the select-ing levers and the shuttles of the rising and falling box and the current of the shuttle whichiisoperated. If the selecting levers weredone away with, it would be necessary that all" these movements should take place in, a single beat of thebatten, that is,

that the exhausted shuttle leaving one compartment of the rising box should arrive at the other-side of the loom, and that all the charging movements would be finished so that the change could take .place. This would be impossible to obtain.

It will be understood that the shuttle box mechanism employed is similar to that commonly" utilized and which is, for example,

described in the United States patent to- Baker and Kip, 655,643, dated August 7, 1900.

The prism 15 as shown in Fig. 2, of course turns through a quarter turn in the direction indicated for each alternate complete swing of the batten or pick; thus when the lever 1 is actuated by a card, it will take place two swings of the batten before the said card can actuate the needle 5. The levers 1 carry at their extremities two button 8 and'9. The left hand. end (Fig. 2) of each lever is pulled downward by a spring 10 suitably fixed to the frame. An oscillatory movement is imparted to the levers by any suitable arrangement such as is opposite a hole in the then horizontal card i 7 to enter this hole to a sufficient depth to enable the other button 9 to come in contact with its corresponding terminal 13 which is suitably insulated. The oscillatory move- 4} memes produced by all the known systems of ratchrts and pawls for rotating this cylinder.

The member 14 raises the lever 12, and the pin 11 raises all of the levers 1. The quarter turn accomplished, 12 is lowered andwith it the levers 1. Fig. 5 shows a horizontal section of a swell for the shuttle. 18 is the frame of the shuttle box formed by a piece of 'wood hollowed out to receive the swell. The use of wood permits of theinsulation of the several boxes from one another. The metallic swell 19 is pressed upon by its spring 20 which is put into'electrical communication with the circuit by a bolt and nut 24,, whose head is sunk in the wood 18. The frames of the compartments of the rising box are formed by the wooden pieces 18 and metallic pieces 22 and 23, the latter forming a series of ledges to support the shuttles. Lips 23 are formed at the extremities of the ledges 23; these ledges 23 themselves like the top 22, do not make electrical contact with the shuttle, since only the insulating faces of the latter touch them. There are as many magnets 29 as there are levers 1 corresponding to each of the compartments of the rising box. The current passing through one of these electromagnets 29 attracts one of the branches of the corresponding bent lever 30, (Fig. 7-), whose other branch raises a corresponding needle 31. These needles are prevented from turning about themselves by a suitable device such, for example, as by the formation of a crook 32, the .parts 31 and 33 of which slide in a piece 33 fixed to the framework. These needles 31 have two loops and 36 between which pass arms 37 having slots 38 in which rides a pin 39 fixed on an arm 40. Means subsequently to be described, are provided for engaging and moving any one of these arms horizontally (Fig. '7). The one that is moved will then itself actuate the arm 40: the slots 38 are'of different lengths, so that the arm 40 will be moved to a greater or less extent according to which arm 37 is moved, and it will by this means determine the selection of a shuttle having the thread of the requisite color in a manner described later on. The other extremities of the arms 37 are narrowed as shown, the narrowed portions con'iprising an inclined part 41, a straight part 42 and a hooked end 43. When one of the levers 37 has been raised by the previously described mechanism, a member 44 extending laterally across the arms 37 and fixed on an arm 45, is brought to slide on the inclined edge 41; said arm can turn about its spindle 46 which is'fixed on the frame to Which is also fixed a stop 47. which limits the fall of 45. Uh 45 is also fixed a flat spring 48 supporting by its branches 49,

two blades 50 and 51 which are fixed on the arm 53. The arm'53 and another arm 53' (Fig. 8) are fixed on a shaft 54 which turns in bearings secured tothe frame. The arm 40 oscillates upon said shaft 54. The arms 37 are drawn toward arm 40 by suitable means such as spiral springs 55. The arm 53 is always drawnto its position ofrest by suitable means such as a spring 56, one end of which is attached to a hook 57 projecting from 53 and the other to the framework at a point 56. The hook 43 of the arm 37 which has been raised by the passage of the current in the corresponding electromagnet 29, engages with an angle block 59 arranged on the batten 60. The corresponding arm 37 is actuated and through it the arm 40 to a degree depending on the length of the slot 38. For each arm 37 there is a well determined'position of the arm 40. In the ascending movement of the arm 37, the inclined edge is in contact with. the pin 44, said pin being therefore raised during the forward movement of said arm and with it, the lever 45, the branch 49 of the spring 48, and the two blades 50 and 51. On its forward movement, the arm 37 actuates the arm 40 which controls the corresponding position .of the shuttle supply magazine 0 which mention has already been made.

Between the confronting notches of the levers 50 and 51, a pin 61 (Figs. 7 and 8) oscillates, said pin being carried by a lever 62 oscillating on a fixed rod 63. To this lever a link 64 imparts a to-and-fro movement in the opposite direction to that of the batten. The upper extremity of 40 carries 'a roller 65 which slides in a slot 66 formed in a plate fixed in front of the lower part of the shuttle supply magazine 67. This magazine can slide between guides and on a base fixed to the framework. It is divided up into vertical compartments equal in number to the different colors of thread employed. The upper part of this magazine carries above each compartment pieces 135 of slightly open U-shape to which are avtached the free ends of the threads of each pirn. When a shuttle has been passed into the batten, and so put'into use, the thread will be out near the selvage of the fabric by shears of any suitable kind. The'movement of the magazine 67 is such that, the color of thread required to be replenished having been indicated by the mechanism previously described, the requisite'shuttle is set automatically into the batten by the following movements. The lever 40 leaving its position of rest is moved in the direction of the arrow 68 (Fig. 9) by that one of the arms 1,147, 188 lift 37 (Figs. 7 and 8) which corresponds to the shuttle to be changed. In this movement the roller 65 riding in the slot 66 (F ig. 9) leads the corresponding compartment of the magazine over an opening 69 formed in the plate 70 fixed to the frame.

By the movement of arms 53 and 53 in the direction of the arrow 72 (Fig. 9) a roller 73 carried by arms 53 and 53 and riding inthe slot 74 formed in a piece 75 fixed to the slide 76, moves this slide which itself moves the pins 77 fixed to each of the guides 78 (Figs. 9,10, 11 and 12) situated on either, side of the stationary plate 70. The guides .78 (Figs. 10, 11, 12 and 13) carry three ledges 79, 80, and 81 (Figs. 10 and 13) which are devised to guide the shuttles in their movement, and to allow to depart from the magazine only that shuttle which ought to, be sent into the batten. The two operations'of selection and delivery of the shuttle occur one after the other.

The position and the length of the ledge 80 are such that it retains by its upper part the shuttle situated above that which is delivered through the opening 69. The function of the ledges 79 and 81 is to guide the shuttles and also to support them by their steel points; .the wear due to this arrangement is much less important than that which would be produced by the sliding of the wooden parts of the shuttles on the plates 70. The object of their movement is to bring the gaps between the ledges 79 and 81, over the opening 69 in the fixed plate 70. The object-of the movement of the magazine 67, as already explained, is to bring the requisite shuttle colu'mn also above said opening 69, whereby, as will be seen, one

shuttle (and only one) has a free passage opened for it, down onto theplate 191. It will beunderstood that the ledges '79, and '81 are free to pass between or beneath the tapered points of theshuttles, consequently the guides 78 when moved, are free .to move relatively to the shuttle magazine and also of course to the stationary plate 7 0. The slide 7 6 carries two triggers 82, one only shown, which are maintained in their raised positions by the action 'of a spring 83. These triggers have for their object to maintain in the requisite position an end plate 84 carried by two rods 85 passing through holes 86 formed in the vertical part of the slide 7 6. These ro'ds have enlarged portions 87 in which are cutnotches 88 to receive detents 89. The plate 84 is constantly engaged byspiral springs 90- surrounding the rods 85 and contained between the vertical part of the slide 76 and the piece 84. A thin plate 191 fixed to the end plate 84 slides under the opening 69. It hasfor its object to prevent a shuttle from passing through the opening 69 before the slide 76 should be entirely pushed back.

91 (Fig. 14) is theshaft carrying cams and supported on one side by the frame and on the other by a bracket 92 fixed to the frame. It turns freely in these supports, and for ease in regulation it is provided at its free extremity with an adjustingwheel '93. The wheel 93 can be operated by hand so as to. adjust the cams 94 and 99, 103 and 110 in their respective positions as regards the length of'the path of the lever 98, as well as the triangular .cam 140. This wheel can also be used to set the cam shaft 91 in any desired position when starting up the loom. v

94 is the cam for oscillating the lever 95 (Fig. 20) the edge of which has an inclined portion 96. This lever turns upon a spindle 97 attached to the frame. Between the spindle 97-and the .free extremity ofthe lever 95 at a suitably chosen point, is pivoted a lever 98, the purpose of which will be arrangement of the inclined edge 96 is such that when 95 rests upon the cam 94 asin Fig. 20, the pin 102 rides uponsaid edge and prevents 101 from engaging the starwheel. lVhen, however, the cam 94 is turned .away from the position shown in Fig. 20,

the lever 95 drops down so that the pawl 101 may engage the star wheel to rotate the cam shaft 91 and this is the case also when the lever 95 is lifted by the link 98, which occurs at the beginning of each cycle of operation and means for doing which will be described more fully.

103 is a cam of the same form as 94 set at 120 to the latter. It works a lever 104 oscillating about 97 and carrying at its extremity a link 105 to the other extremity of which is suitably connected a' lever 106 oscillating around a pin 107 fixed to the frame and carrying at its other extremity a pin 108 whose position can be regulated in a slot 109. This pin is adapted to operate in a known manner the revolving box,by means of pawls and ratchets carried on. a system of levers of which one engages with 108. It will be understood that the revolving box .is normally held in proper position with respect to the picking mechanism and the batten by means of a spring pressed plate (not shown) carried by the shaft of the box in the manner shown inthe patent to Baker et al. Serial Number 636,706, of August 22, 1899. .Now the.,,system for turning the revolving box, which has just been mentioned,

'is only partly shown in the drawings but, broadly speaking, is also similar to the system shown in the patent to Baker mentioned above, particular reference being "made to Figs. 4 and 6 of said patent. My arrangement (part of which is shown in Fig. 21) consists of a Tshaped lever 180 pivotally mounted on the batten. This lever 180 car ries a pawl thereon on one of two horizontal projections extending on both sides of the lay which cooperates with four pins 183 carried on the end of the revolving box to turn the revolving box 90 at each complete operation of the lever 180.

It will be apparent that my arrangement is equivalent to the pawl and pins shown in Baker above mentioned. The operation of the lever 180 in one direction is caused by its striking the pin 108 when the latter has been raised in the manner previously described. This causes the pawl to engage the pins and the reverseswing of the batten causes the lever 180 to strike the pin 181, which is adjustably mounted in the slot 182 of the bar 183 fixed to the frame and projecting toward the batten so as to return the lever 180 and its pawl (not shown) to their normal positions. The revolving box is held normally in proper angular position with respect to the batten by means of four V- shaped teeth formed on the head of the box which is opposite the lever 180. These teeth engage similar teeth on a spring pressed nut 18% which is mounted on the axle 217 so as to move axially thereof but sothatitcannot rotate thereon. When the lever 180 has been given one complete oscillation by successive contacts withpins 108 and 181, as just described, the pawl carried on the inner face of the lever cooperates with the pins carried by the box to turn the box 90 or the distance between two successive V-shaped teeth. This said system is adopted on looms at present in use which employ a revolving box, only the position of the pin 108 being modified in the present system according to which it is placed on the lever 106, and iS adjustable in the slot 109. During the nor mal course of weaving the box aforementioned is not revolved. This is only done when replacing a shuttle as hereinafter described.

110 is a cam of the same form as 103. It is set at 120 to the latter and actuates a lever 111 (shown in Fig. 21 but not in Fig. 20) turning about 97 and attached to a link 112.

14:0 19) is a cam of equilateral triangular formation having rounded edges. A plate 1 11 is adapted to bear upon either of the plane faces of the cam, said plate being maintained in close contact therewith by a spring 11 so'that the spindle 91 should retain the position determined by the rotation of the star wheel.

113 (Figs. 21 and 22) is a toothed sector fixed to the axis or arbor 11 1 (Figs. 20, 21

and 22) the movement of the sector beingrendered rapid by the action of a spring 137 fixed to the frame at 138. This axis 114:

other extremity at 122, a pin 123' riding in;

'said slot and being fixed on a catch 124 turningfreely on the spindle 63 (Figs. 7 and 22). At 119 is further firmly fixed a member 125 called a dog which has for its object to raise the swell of that compartment of the revolving box which is to receive the new shuttle, when the revolving box is rotated.

126' (Fig. 22) is a partially toothed sector turning freely around its spindle 127 fixed on the frame. On this sector are fixed three pivot pins 128, 129 and 130. 128 slides in the slot 139 out in thehead of the lever '98 (Fig. 22). V

129 carries a rod 131 (Fig. 22) which brings back thedetent 89 (Fig. 9). This rod is surrounded by a spiral spring 132 (Fig. 21) bearing at one end on a ring 133. fixed to the rod 131 and at the other on a lever 134 fixed on the spindle which carries the detents 89. 130 slides in the slot 130 in the head of the lever 112 (Figs. 21 and 22).

Before explaining the working of the mechanism as a whole, it would be well; first, to describe further the action of the revolving box. During the normal course of weaving it does not revolve; shuttles picked from their compartments in the rising box'are always received in the same compartment of this revolving box and then picked back again; in Fig. 23 this compartment is designated at A itwill be noticed that the compartment 1) that faces toward the shuttle mechanism is empty. The shuttle in B is the one last exhausted before A and that in C is the one that preceded 3. Suppose now that the shuttle in A which is exhausted has been picked for the last 7 time into the revolving box; the following operations will then occur as subsequently described. A new shuttle will be fed to D that 1n C Wlll be released and drop down (Fig. 25), and the box vwill then make a quarter turn in a contra-clockwise direction (Fig. 23) thus presenting again an empty compartment viz. C toward the shuttle supply mechanism. In this position the box will remain during the next stretch of normal weaving; at the next change, the shuttle in compartment 13 will be dropped down, and at the next after-the shuttle in compartment A will fall. The 'shuttle is picked alternately from the rising box to the revolving one and vice versa, each pick occurring when the batten is in the position such as shown by Fig. 23, which I willcal'l the extreme point of its backward movement. To explain the working of the different members I shall suppose that the batten has just passed that point and is moving forward thereby beating the weft while the shuttle has entered into the multiple rising box- In the following-description we will suppose that the driving mechanism of the loom is on the left; The members shown in Figs. 2, 3, 4, 5, and 6 are to the right of the loom when looking at it, and the other are to the left. \Ve have supposed a four colored loom to be used, any warp being employed. During the forward movement of the batten above referred to, (which we will call the first) the card on the cylinder 15 is brought against the needles 5, and that needle 5 which is opposite to a hole engages therewith in the usual manner. The levers 1 liberated by the pin 11 of the lever 12, lean upon the top card of the cylinder. A contact is made corresponding to the hole engaged on this card. If the pirn of the shuttle corresponding to this hole is'not finished, the circuit not being closed, no current will actuate the corresponding electro-magnet 29. If on the contrary, the pirn corresponding with the hole in the card is almost empty, the current will traverse the shuttle and close the circuit of the corresponding electro-magnet 29; thereupon" the lever 30 raises the needle 31 which in its turn raises the arm 37 supported between its loops 31 and 35.

In the first backward movement of the .batten 60, that is, one in the direction of' the arrow 138 (Figs. 7, 23, 24 and 25), the angle block 59fixed on the arm-thereof engages the hook. The arm 37 moves in its turn the arm 40 through a distance proportioned to the length of the slot 38. The arm 40 moves that compartment of the magazinecorresponding to the colored thread required to its position regulated by the length of the slot 38 and the position of the opening 69. .In this same backward movement of the batten, the arm 37' raises, by means ofthe pin 41 and the lever 45, its spring 19 and the two hooked arms 50 and 51.- The arm 51 being engaged by the pin 61 on the arm 62 (Fig. 24) receives a reverse movement from that of the batten and moves the arms 53 and 53 in the direction of the arrow 72 and they engage the slide 76. In its forward movement (for it moves in the reverse direction to the batten), the slide,

by means of the pins 77 engages the guides shown in Fig. 25.

abled to enter without resistance into the 78. At this moment the shuttle which is over the opening 69 (from 79) is also clear of the ledges 79 and 81 and so falls on the slide 76 in front of the plate 84. The shuttles placed in.the same compartment above nected to the arbor 114: of the sector 113,-

serves to turn the latter in a clockwise direction (as shown by the arrow 135 in Fig. 22).

and the pin 123 raises the catch 12 1. In its rotary movement the sector '113 (see Fig. 21) turns the sector 126 which by the pin 128 raises the link 98 which itself raises the lever 95 and removes the edge 96 from the range of movement of 102, thereby allowing the pawl 101 to engage with a tooth of the star wheel. 129, which, by the combination of the rod 131 and the lever-131, raises the detents 89 from engagement with the notches 88 and so releases the rods 86 (Fig.- 9) of which 87 are extensions. At this moment the batten is at the extreme point in its first backward movement and the spent shuttle picked for tary one.

In the second forward. movement of the batten in the direction of arrow 72 to beat up the pick of weft supplied by the shuttle the last time from the rising box to the rojust thrown, the revolving box will be carried forward with it. and will present its empty compartment toward the charging slide 76. This slide moves in the reverse direction to that of the batten (that is, in the direction of arrow 138 by means of the arm 62 which actuates the blade 50 c0nnected with the arm 53, by this arm and the shaft 54:, with the arm 53 (Fig. 8) the arm 62 effects this by virtue of the engagement of 61 with the hooked beak on 50, which by its shape, holds on to 61 when in the position The full shuttle is enempty compartment of the revolving box in consequence of the raising of the swell by the dog 125 fixed in front.

The insertion of the new full shuttle in the empty compartment of the revolving box effected by the abutment of the Vertical part of the trigger 82 against a fixed stop 82.(see Fig. 25 attached to the frame at such a point that at this moment the batten is at the end of its forward stroke. The horizontal portion of the trigger 82 is lowered, and the plate 81 is shot quickly forwardby the. expansion of the springs 90. ,84epushesfor This sector actuates the dog 125 and. the lever 119which itself by the link 121 a maniac ward the new shuttle which having passed through the opening 69 has fallen on the horizontal part of the slide 76. At the same time, the finger 121, which is also raised, en-

gages under the swell of the lower compartthe revolving box charged with the new' shuttle, frees itself from the dog 125 which allows the swell of this compartment to press against the aforesaid shuttle in the ordinary manner. The pawl 101 turns the star wheel 99 through one third of a.revolution in the direction of the arrow 100. In consequence of this rotation the cam 94 is lowered, the cam 110 raises the lever 111,

shown in Fig. 21 but not in Fig. 20, which raises in its turn the link 112 which actuates the pin 130 which moves the large sector 126 in the direction of the arrow 136 (Figs; 21 and In thismovement the pin 129 pushes the rod 131 which by the lever 134 lowers the detents 89. By this same movement the pin 128 frees the link 98 which allows the lever 95 to drop to such a level that its edge 96 assumes another position in which it cannotprevent the engagement of the pawl 101 and the wheel 99. Lever 95 is lifted subsequently into such a position as to prevent the cooperation between the pawl 101 and the wheel 99 by means of the cam M which automatically lifts the lever 95 at a certain point in the revolution of the arllUl' 91. extends the spring 137 which is connected to sector 113 until the point of connection between the sector 113 and the spring fallsbelow the pivot point of the sector, when the spring serves to give the sector a quick snap to the limit of its free movement in of the batten, the arm 62 catches the projection on the lever 51, thus moving the arms 53, 53 in the direction of the arrow '72 (Fig. 9). The slide 76 thus moves in the same direction and, by reason of its abutment against 87, carries the rods 85 and plate 81 forward with it, and the detents S9 engage in the notches 88. The sector 126 during this same movement of the batten rotates the sector 113 through a quarter of a turn in the direction of the arrow 139 (Fig. 22), the sector 126 being turned in the direction of arrow 136 (Fig. 22) by means of link 112 which is lifted at this juncture by the cam 110 acting through lever 111. By this movement it lowers the arm 119 and by In its lifting movement the link 1 12 7/ means of the link 121 the finger 124. It also lowers the dog 125 so that the members 12 1 and 125 are returned to their normal or nonoperative positions.

During the third forward movement of the batten (in the direction of the arrow 72) 62 engages 50 and serves to move the slide 7 6 in the direction of the arrow 138 The detent 89, however, engaging in 8S, prevents the plate 8l from also moving and consequently the springs 90 are compressed, and the triggers 82 temporarily depressed as they pass under the edge of 8 1, are forced up again by the spring 83 andbear against the outside of Set. The slide 7 6 and arms 53 and 53 are subsequently returned to the normal position shown in Fig. 23 by the action of the springs 71 and 56. 'At the end of its third forward movement (in the direction of the arrow72) the lay sword, by means of the pawl 101 engages the star wheel 99 and turns it through a third of a turn as it moves backward for the third time. By this rotation the cam 110 is put out of action and the cam 103 thrown into action, said cam, by means of the levers 10%, 105 and 106, leaves the pin 108 in the position to assist in turning the revolving box through a quarter of a turn during the fourth forward-or backward movement of the batten.

In its fourth backward movement, the lay sword turns the star wheel 99 through a third of a turn. lit puts out of action the cam 103 and throws into action the cam 94: which lifts the lever 95 into the position in which, as before mentioned, the pin 102 will ride upon the edge 96 thus all the mechanism placed on the left side of the loom is thrown out of action until another pirn should be shown by the selector to be finished. ll claim- 1.
